Learning history from Hollywood movies and don't pay attention to the actual events can easily make you misunderstood what really happened.
The Germans during ww2 were much more frightened of the Soviets than the Americans. The fact is Germany sent their best Wermacht to the Eastern front against the Slavics who kept coming like zombies. The soviet leadership was total sh/t. Soldiers were poorly equipped, poorly trained but they kept coming in huge numbers. They die in the millions, the number of soviet military deaths is almost ten times the casualties of us + Germany. To attempt breaking the soviets spirit, for every German soldier killed, the German would kill 50 soviet pow or civilians. Doesn't work as the soviets don't give a ******* ****. The hungry soviets, were known to cook the German pow to eat, the Germans were even more afraid. Bloody and crazy like hell.
Matter of fact, the German army sent to fight the Americans at Normandy were mostly German's reserve units. So some historians question the success of the battle. Majority of the German best military units were having showdown with the soviets. When the soviets were fighting against Germany, the German army were at the prime with strong morale, well trained and well equipped. When the Americans were fighting, the Germans were already starting to lose. It was the soviets who made the first German Marshal to surrender and locked up alot of the German's resources and military in the eastern front. If Hitler did not underestimate the soviets and declared war against them, things could be very different.
One of the crazy battle for the Americans should be the battle of Okinawa where they meet the relentless Japanese troops. Iirc USA had 500k versus japs 100k. 90 over percent of the japs died, they fought all the way.
No German troops landed on America soil Iirc. Casualties at home is at the minimal. All fights were on foreign soil. This is very witty. Even today, USA has a approach to try shifting main battleground to other countries.
